Comparison of Patient Comfort and Acceleration Exposure During Lifting and Loading Operations Using Manual and Powered Stretchers.

Objectives: To compare the effects of powered and manual stretchers on participants' perceived comfort and measured acceleration during lifting and loading operations.

Methods: This non-randomized, laboratory-based crossover study involved forty-one participants (thirty-one firefighters and ten third-year paramedic students) who served as simulated patients experiencing lifting, lowering, loading, and unloading maneuvers using manual and powered stretchers. Four stretcher types were evaluated: one powered stretcher (Power-PRO XT) and three manual stretchers (Matsunaga GT, Exchange 4070, Scad Mate), with each group using the manual stretcher they routinely operated.

Optimal duration and timing of basic-life-support-only intervention for patients with out-of-hospital cardiac arrest.

To elucidate the relationship between the interval from cardiopulmonary resuscitation initiation to return of spontaneous circulation (ROSC) and neurologically favourable 1-month survival in order to determine the appropriate duration of basic life support (BLS) without advanced interventions. This population-based cohort study included patients aged ≥ 18 years with 9132 out-of-hospital cardiac arrest of presumed cardiac origin who were bystander-witnessed and had achieved ROSC between 2018 and 2020. Patients were classified into two groups based on the resuscitation methods as the "BLS-only" and the "BLS with administered epinephrine (BLS-AE)" groups.

Neurological outcomes in traffic accidents: A propensity score matching analysis of medical and non-medical origin cases of out-of-hospital cardiac arrest.

Aim: This study aimed to comprehensively compare the characteristics of out-of-hospital cardiac arrest (OHCA) with medical and non-medical origins attributed to traffic accidents and explore the potential association between the cases with a medical origin and neurologically favorable outcomes.

Methods: In this retrospective nationwide population-based study, baseline data were collected between January 2018 and December 2020. We analyzed 5091 OHCA associated with traffic accidents on the road scene.
